Abstract

In one aspect, the invention provides a body comprising particles containing an insulating aerogel material intermingled with particles containing a phase change material, and a binder forming a matrix retaining the intermingled particles. In another aspect, the invention provides a method of forming an insulating body comprised by applying first and second streams onto a substrate; the first stream comprising a binder and the second stream comprising particles containing aerogel material; and simultaneously applying a phase change material onto the substrate.

Claims (22)

1. A body comprising: particles containing an insulating aerogel material intermingled with particles containing a phase change material (PCM), and a binder forming a matrix retaining said intermingled particles.
2. The body of claim 1 wherein said phase change material undergoes a solid-liquid transition.
3. The body of claim 1 wherein said PCM is encapsulated in a capsule.
4. The body of claim 3 wherein the capsule resists degradation by said binder.
5. The body of claim 1 wherein the phase change material comprises wax.
6. The body of claim 1 wherein the phase change material comprises wax encapsulated in a capsule.
7. The body of claim 1 wherein the phase change material undergoes a phase change at a temperature greater than about 100 degrees Fahrenheit.
8. The body of claim 1 wherein said aerogel material comprises a silica-based hydrophobic material.
9. The body of claim 1 wherein the particles containing aerogel have a particle size in a range of about 6 micrometers to about three millimeters.
10. The body of claim 1 wherein the particles containing phase change material have a particle size in a range of about 15 to about 40 micrometers.
11. The body of claim 1 wherein said phase change material undergoes a solid-solid transition.
12. A body of material comprising: an insulating aerogel material intermingled with a phase change material, said phase change material capable of storing thermal energy as latent heat of phase change.
13. A method of forming a thermally insulating body comprising:

a. co-depositing onto a substrate, particles containing aerogel material, particles containing phase change material, and a solution containing a binder and a carrier; and b. removing the carrier to form a solid thermally insulating body on the substrate.
14. The method of claim 13, wherein the co-depositing is conducted by discharging under pressure said aerogel-containing particles and said phase change material containing-particles onto a substrate while discharging a dispersion of said solution onto the substrate.
15. The method of claim 13, wherein the binder includes silicone.

17. The method of claim 13, wherein the removing of the carrier is conducted by drying.
18. The method of claim 13, wherein the solution is contained in a first stream and the particles are contained in a second stream.
19. The method of claim 18 wherein the first stream is interior of the second stream.
20. A method of forming an insulating body comprising: applying first and second streams onto a substrate while simultaneously applying a phase change material (PCM) onto the substrate; the first stream comprising a binder and the second stream comprising particles containing aerogel material.
21. The method of claim 20, wherein the PCM is contained in particles that are applied via a third stream.
22. The method of claim 20, wherein the PCM is contained in particles that are included in the second stream.
